Equipped with a TDA7492PE Dual-BTL Class-D digital amplifier IC manufactured by ST Microelectronics of Switzerland. A custom-made capacitor is used in the input coupling section. High-current compatible magnetically shielded (closed-circuit) type SMD inductor I used ITW (PAKTRON) RA series capacitors (MIL-spec) for the filter capacitors in the output stage. The power supply smoothing capacitors are made in Japan and feature high-capacity, low-impedance grade capacitors. Equipped with a DIP switch for selecting the base gain setting. Affordable price, high resolution, and a design that matches other devices. AC adapter required (sold separately) DC12V/current capacity 2A or higher DC jack 5.5mm x 2.1mm (center positive) FX-AUDIO- brand digital stereo power amplifier (50W mid-range output class) standard model Equipped with ST Microelectronics' "TDA7492PE" digital amplifier IC, it enables a maximum of 48W x 2ch stereo output. Designed for use as a simple power amplifier, this model offers excellent sound quality at an affordable price. Based on the reference circuit, and without omitting any circuits that affect sound quality, circuits that can improve sound quality at a low cost are efficiently arranged. Furthermore, by using high-quality components, including custom-made audio-specific parts, in key areas where sound quality improvement can be expected, we have achieved high-resolution and flat sound quality. [Product Features] ◆ Equipped with a Swiss ST Microelectronics TDA7492PE Dual-BTL Class-D digital amplifier IC. Maximum output 48W + 48W @ 24V This digital amplifier IC boasts high efficiency (over 80% conversion efficiency), low power consumption, and high output power. The TDA7492PE retains an analog-like listening experience while featuring a clear, high-resolution sound with minimal distortion. Despite its small size, this unit delivers surprisingly high output power, capable of driving even large speakers. ◆The input coupling section uses custom-made capacitors with a reputation for excellent sound quality. For the input coupling capacitors, which significantly affect sound quality, we used audio-grade polyester film capacitors specially manufactured for FX-AUDIO- limited production items. These custom-made capacitors were initially used in limited edition models such as the TUBE-00J LIMITED, and after receiving overwhelmingly positive feedback and support, they led to their mass production in the TUBE-00J UNLIMITED model. ◆High-current compatible magnetic shielding (closed circuit) type SMD inductor By reducing the inductor's line impedance and designing it to handle high currents, sound distortion caused by impedance is reduced. Furthermore, because it is a magnetically shielded inductor, there is no magnetic field binding, guaranteeing the original filter performance and stabilizing the frequency characteristics as designed. ◆The filter capacitors in the output stage are ITW (PAKTRON) RA series capacitors (MIL-spec). To meet MIL standards, special manufacturing methods, such as production in a reduced-pressure environment, are employed, resulting in superior characteristics that prevent moisture and air from entering, contributing to high-resolution and clear sound quality. We have actively used this proven capacitor, which has been highly praised for its high resolution and clear sound quality in models that prioritize sound quality, and it also works well with the input coupling capacitor, further improving sound quality by adding a high resolution and clear sound characteristic. ◆Equipped with high-capacity, low-impedance, Japanese-made capacitors for power supply smoothing. It provides a clean and stable power supply, contributing to an overall improvement in sound quality. ◆ Equipped with a DIP switch for selecting the base gain setting. The unit offers four base gain settings—20.8dB, 26.8dB, 30dB, and 32.8dB—which can be easily switched using a DIP switch located on the back of the unit. It can be adjusted and combined to match the type, capabilities, and gain of the preamplifier. *Default state (ALL OFF): 20.8dB *Please switch the gain setting switch with the power turned OFF. - Backlight effect on the back of the volume knob - Gold-plated RCA input terminals, gold-plated speaker output terminals, compatible with both straight and banana plugs. The aluminum alloy casing is lightweight and highly rigid, and the hairline finish gives it a premium feel. The body is further treated with anodizing to make it more scratch-resistant. The control holes on the front panel are CNC machined and tapered for a beautiful design. [Notes] The product warranty period is 6 months from the date of purchase. - Always turn off the power to the unit before adjusting the gain. • This product does not include a power supply. Please purchase an AC adapter separately.
